On the other hand, if it is position beyond non-traveling-position that the absolute value of the rotating speed of driving engine 12 becomes more than specified value or shift pattern, then be judged as having a mind to make signal circuit 15C be changed to the possibility lower (possibility that namely there occurs the exception of disconnection fault etc. is high) of dissengaged positions, thus forbid making the side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions (namely negative cuts off license).
And then, storage battery ECU8 is when permitting to make at least side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 (such as side of the positive electrode contactless switch 22 and negative side contactless switch 23 both) to become dissengaged positions, such as, by indicating each contactless switch 61p of the conducting between the quick charge device 2b of enable cut-out outside vehicle and electrical storage device 3, 61n becomes dissengaged positions, or indicate charging to stop to charger 52, or to quick charge device 2b or the charging unit 2a instruction charging stopping of outside vehicle, forbid the charging from external recharging apparatus 2 to electrical storage device 3.
In addition, storage battery ECU8 such as makes after at least side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions in license, when making at least side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions actually, the executory situation of this dissengaged positions is informed to driver by notifying device 44.
In addition, such as, when forbidding making the side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions, situation higher for the possibility of the exception that there occurs disconnection fault etc. is informed to driver by notifying device 44.
In addition, storage battery ECU8, when such as detecting signal circuit 15C and changing to the situation of dissengaged positions from coupled condition and forbid that the side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions (namely negative cuts off license), will represent that the cut-out NACK messages that negative cuts off license is stored.
Then, such as when detecting signal circuit 15C and changing to coupled condition from dissengaged positions, even if until delete the storage cutting off NACK messages, permit that the condition making at least side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions is all set up, also forbid making the side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions (namely negative cuts off license).
The relay control device 10 of present embodiment possesses above-mentioned formation, and next the action of this relay control device 10 is described.
First, in the step S01 shown in Fig. 5, whether decision signal circuit 15C changes to dissengaged positions from coupled condition.
When this result of determination is "No", proceed to end.
On the other hand, when result of determination is "Yes", step S02 is proceeded to.
Next, in step S02, under the testing result of tachogen 42 is normal state, judge the whether not enough specified value of absolute value of the rotating speed of driving engine 12.
When this result of determination is "Yes", proceed to step S05 described later.
On the other hand, when result of determination is "No", step S03 is proceeded to.
Then, in step S03, be judged as that the possibility of the exception that there occurs disconnection fault etc. is higher, forbid making the side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions (that is, negative cuts off license).
Next, in step S04, situation high for the possibility of the exception that disconnection fault etc. occurs is informed to driver, proceeds to end.
In addition, in step S05, under the testing result of shift pattern sensor 43 is normal state, judge shift pattern whether as non-traveling-position (such as stop position or Neutral Position etc.).
When this result of determination is "No", proceed to above-mentioned step S03.
On the other hand, when this result of determination is "Yes", step S06 is proceeded to.
Then, in step S06, license makes at least side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions, forbids the charging from external recharging apparatus 2 to electrical storage device 3.
Next, in step S07, notify that at least side of the positive electrode contactless switch 22 of electrical storage device 3 or the dissengaged positions of negative side contactless switch 23 are in execution to driver, proceed to end.
In addition, in above-mentioned process, such as step S03, shown in 04, be judged as that the possibility of the exception that there occurs disconnection fault etc. is higher, thus when forbidding making the side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions (namely negative cuts off license), even if perform the disconnection of ignition lock afterwards and the vehicle that causes stops and the conducting of ignition lock and the vehicle that causes starts again, also maintaining makes the side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become forbidding (namely cutting off the negative of license) of dissengaged positions.
Below, illustrative examples as when shift pattern is stop position, in situation about intentionally interlocking connector 14 being pulled down from interlocking connector splicing ear portion 15.
Such as, moment t1 shown in Fig. 6, the not enough specified value (such as zero) of the absolute value of engine speed and shift pattern be stop position state under, along with representing that interlocking connector 14 interlocking connector be installed in interlocking connector splicing ear portion 15 installs signal from Significant Change to non-effective, starting to cut off to perform and determining the timing that time meter carries out.
Then, perform in cut-out and determine that the clocking value of time meter reaches the moment t2 of the clocking value of regulation, to permit that the cut-out execution flag value making at least side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become dissengaged positions is switched to " 1 " from " 0 ", at least side of the positive electrode contactless switch 22 or negative side contactless switch 23 are set as dissengaged positions.
Then, such as during moment t3 to moment t4, under the state that at least side of the positive electrode contactless switch 22 or negative side contactless switch 23 are set as dissengaged positions, even if such as shift pattern changes to beyond stop position, namely beyond non-traveling-position, be also maintained until the dissengaged positions of Shaozheng pole side contactor 22 or negative side contactless switch 23.
Then, such as moment t5, under the state that at least side of the positive electrode contactless switch 22 or negative side contactless switch 23 are set as dissengaged positions, change to effectively if interlocking connector installs signal from non-effective, then reset the clocking value cutting off and perform and determine time meter, the mark value cutting off execution flag is switched to " 0 " from " 1 ".Accompany therewith, the side of the positive electrode contactless switch 22 of electrical storage device 3 and negative side contactless switch 23 be switched to coupled condition, at least the dissengaged positions of side of the positive electrode contactless switch 22 or negative side contactless switch 23 is removed.
Then, such as moment t6 later, if shift pattern is switched to beyond stop position, namely beyond non-traveling-position, thus such as perform the acceleration operation etc. of driver.Such as later in moment t7, drive driving engine 4 by the electric power of electrical storage device 3, engine speed is transformed to increases tendency.
Below, illustrative examples as in the traveling of elec. vehicle 1, interlocking connector 14 pull down from interlocking connector splicing ear portion 15 situation (or signal circuit 15C occur broken string situation etc.).
Such as, moment t1 shown in Fig. 7, under the absolute value of engine speed is more than specified value and shift pattern is the motoring condition of elec. vehicle 1 beyond non-traveling-position, it is non-effective for installing signal from Significant Change along with interlocking connector, starts to cut off the timing forbidding determining that time meter carries out.
Then, after cut-out forbids determining that the clocking value of time meter reaches the moment t2 of regulation clocking value, by forbidding that the mark value making the side of the positive electrode contactless switch 22 of electrical storage device 3 or negative side contactless switch 23 become the cut-out prohibition flag of dissengaged positions is switched to " 1 " from " 0 ", side of the positive electrode contactless switch 22 and negative side contactless switch 23 are maintained coupled condition.
Then, such as moment t4 later, under the state that side of the positive electrode contactless switch 22 and negative side contactless switch 23 are maintained coupled condition, even if the absolute value of such as engine speed is not enough specified value (such as zero) and shift pattern changes to stop position, also maintain and forbid the state that the cut-out making side of the positive electrode contactless switch 22 or negative side contactless switch 23 become dissengaged positions is forbidden.
Then, such as moment t6, forbidding under the cut-out illegal state making side of the positive electrode contactless switch 22 or negative side contactless switch 23 become dissengaged positions, change to effectively if interlocking connector installs signal from non-effective, then cut off and forbid that the clocking value determining time meter is reset, the mark value cutting off prohibition flag switches to " 0 " from " 1 ".
